test: automate determining non-en locales for broken-link-checker test to ignore 🌋

[darcywong00]

Addresses #712 (comment)

Excluding all locales except en will not scale well. I wonder if there is a better way -- can we build a scripted filter using the api published at broken-link-checker?

I'm applying to the base branch master so we can compare the CI link checker to existing runs
This passing run took 13m 23s after skipping /downloads/releases

The one for #979 took 26m 49s

This updates ci.yml and build.sh to determine the list of non-en locales to ignore (along with /downloads/releases) for the broken-link-checker CLI to run.

Test-bot: skip

An alternative (less drastic) way may be to use BASH to generate the list of excludes

like

Suggested change

	node blc_test.mjs | tee ../blc.log
	# determine non-en locales to ignore
	readarray -t ignoresArray <<< $(find ./_includes/locale/strings/keyboards/ -maxdepth 1 -name '*.php' ! -name "en.php" \
	-execdir basename {} .php ';')
	local baseURL="http://localhost:8053"
	local ignoreStr=()
	for locale in "${ignoresArray[@]}"; do
	ignoreStr+=" --exclude ${baseURL}/$locale/*"
	done
	# echo "ignoreStr: ${ignoreStr[@]}"
	npx broken-link-checker ${baseURL}/_test --recursive --ordered ---host-requests 50 -e --filter-level 3 ${ignoreStr} | tee blc.log

Yep, I reckon this would be easier for now but I think the .mjs would be more maintainable long-term. Not sure if we have bandwidth to complete the long-term approach.

(Another area we could exclude is the /downloads/releases for every single release)

[darcywong00]

split the long-term suggestion to #721
